1. Make sure the Tx (transmitter) and Rx (receiver) are set to the same channel/frequency.
2.Power for the Tx and Rx should be between 10.5 - 13.6 VDC, as lipos voltage can go below that.
3. Make sure the video and ground wires of the camera is connected to the video and ground wires of the transmitter. (see image: https://hobbywireless.com/images/support_photos/non_plug_n_play_mod.jpg)
4. Check the camera by connecting it directly to a display monitor to make sure the camera is not faulty, or try different camera if you have other.
5. Important, make sure you use the AV cable that came with your receiver, other cable might look the same and fit, but internally they are wired differently.
6. If your receiver has the "A/B" switch. leave it on factory default unless the use of this switch is required in the instructions.

1- Don’t fly too low when your model is too far. It migh cause your model to crash.
2- When installing your system into a model, try to keep your wireless video system as far as possible from the R/C system.
3- Always keep your a/v transmitter in a well ventilated place. NEVER confine the a/v transmitter where air flow is scarce, otherwise it can overheat and permanently damage it .

7. Plug and Play Transmitter Functions:

How to adjust the built-in microphone's volume. Just punched the clear shrink wrap on top of the volume controller by using a needle or something with a sharp pointed end.Then with right sides of its or small flat head screwdriver gently turn clockwise to increase the volume, or counterclockwise to lower the volume.

8. Do not force the connectors of your plug and play transmitter pulling them out without properly unlatching them. This may slide the connector house to slide off shortening the pins inside causing the camera not to work, or intermittently lose video.

9. Poor video reception or range can be caused by many factors such as

Low quality receiver and transmitter
Stock whip antennas must to be in the same position straight vertical. If one antenna is straight vertical and the other is leaning to any direction, it will aftect the performance.
Multipath is a very common issue.

10. Examples of Multipath. (Click on the pictures to enlarge). A good set of circular polarized antennas is the best way to deal with multipath issues.

14. How make make connections for your "non-plug" and play 12v transmitter with 12v cameras.

15. T512 and T524 transmitters. It's not plug and play version, you will have to use the heavy RCA connectors or customize your own. See next illustration below. The cable has a built-in voltage regulator with that can be powered using 5 - 12 VDC MAX! Using 2S 7.4V lipo is more adequate.

16. How to remove the RCA connector from the transmitters (not plug and play version). Test your transmitter before cutting the wires. * Make sure the wire are well insulated.

17. Transmitter module wires configuration and proper way to use them? (some transmitters uses 12 v others 5v to be powered on, any voltage above 5v will damage the unit, see picture above)

18. If you want to connect the camera to the transmitter without messing with soldering, see the two illustrations below. Here is an example with our FPVCAMs with a built-in microphone

19. Here is an example with our SN555, SN777, PETITE, KPC650 without built-in microphone. - No plug and play version -

20. How to change your heavy camera stock connectors to servo type connector. This precedure is for cameras that don't have plug and play cable.

21. This illustration applies for all the TR (transmitter + receiver) - No plug and play combos -

22. Make sure your transmitter is connected corrected making sure the polarity is not reversed. Also do not exceed the maximum voltage recommended by the manufaturer, otherwise it will cause permanent damage and void the warranty.?
